Description
(A)酸性基含有(メタ)アクリル系重合性単量体を少なくとも一部として含有する(メタ)アクリル系重合性単量体成分を100質量部
(B)水を1〜25質量%含有し、20℃での水への溶解度が20g/100ml以上である揮発性有機溶媒を75〜99質量%含有する含水溶媒を50〜600質量部
(C)アルキル基が炭素数4以下のものである低級アルキルメタクリレートを重合させた、ポリ低級アルキルメタクリレートを0.05〜10質量部
(D)有効量の化学重合開始剤
を含有してなる歯科用接着剤であって、
該歯科用接着剤が
(A)(メタ)アクリル系重合性単量体成分を含む組成物(I)と、
(C)ポリ低級アルキルメタクリレートを含む組成物(II)と
に分包されてなることを特徴とする歯科用接着剤である。
接着材層の疎水性を向上させることから、硬化後の接着材層の吸水性を下げて長期間安定的に高い接着強度が得られるようにする効果がある。
本発明の歯科用接着材は、(C)(メタ)アクリル系ポリマーを配合することで均一な厚みのある接着材層を形成させ、接着強度を向上させているが、接着材層の耐久性を更に向上させる目的から、(E)ヒュームドシリカを添加することが好ましい。本発明において(E)ヒュームドシリカとは、火炎加水分解法によって製造された非晶質シリカであり、煙霧質シリカとも別名されるものである。具体的には、四塩化ケイ素を酸水素炎中で高温加水分解させることで製造することができる。該方法によって製造されたシリカは、透過型電子顕微鏡で測定した任意の100粒の平均1次粒径が5〜100nm程度、好適には7〜30nmであり、上述のように緩やかな3次凝集構造をしている。

(1)粘度の測定方法
粘度測定試験サンプルは、(A)(メタ)アクリル系モノマー、(C)(メタ)アクリル系ポリマー、及び(E)ヒュームドシリカが含まれる場合には該成分も配合し、均一になるまで混合撹拌して調製した。混合物が均一にならない場合は、上記混合物に適当量のアセトンを混合して均一になるまで撹拌し、その後、該混合物の濃縮乾燥を行い、アセトンを除去後、粘度測定試験サンプルとした。
a)接着試験片の作製方法
屠殺後24時間以内に牛前歯を抜去し、注水下、#600のエメリーペーパーで唇面に平行になるようにエナメル質および象牙質平面を削り出した。次に、これらの面に圧縮空気を約10秒間吹き付けて乾燥した後、エナメル質および象牙質のいずれかの平面に直径3mmの孔の開いた両面テープを固定し、ついで厚さ0.5mm直径8mmの孔の開いたパラフィンワックスを上記円孔上に同一中心となるように固定して模擬窩洞を形成した。この模擬窩洞内に歯科用接着材を塗布し、20秒間放置後、圧縮空気を約10秒間吹き付けて乾燥し、必要に応じて(使用した歯科用接着材の重合開始剤が光重合開始剤の場合において)歯科用可視光照射器(トクソーパワーライト、トクヤマデンタル社製)にて10秒間光照射した。更にその上に歯科用コンポジットレジン(エステライトPクイック、トクヤマデンタル社製)を充填し、可視光線照射器により10秒間光照射して、接着試験片を作製した。その後、レジンセメント(ビスタイトII、トクヤマデンタル社製)を用いて、コンポジットレジン上に金属製アタッチメントを接着した。
b)接着試験方法
接着試験片を37℃の水に24時間浸漬後、引張り試験機(オートグラフ、島津製作所製)を用いてクロスヘッドスピード2mm/minにて引張り、エナメル質または象牙質とコンポジットレジンの引張り接着強度を測定した。1試験当り、4本の引張り接着強さを上記方法で測定し、その平均値を接着強度として測定した。
(A)(メタ)アクリル系モノマーにおける酸性基含有(メタ)アクリル系モノマーとして39gのPM、その他の非酸性(メタ)アクリル系モノマーとして24gのBisGMA、16gの3G及び21gのHEMAと、(B)含水溶媒の揮発性有機溶媒として149gのアセトンならびに16gの蒸留水、(C)(メタ)アクリル系ポリマーとして1gのPMMA、(D)重合開始剤として0.15gのBMOV、(E)ヒュームドシリカとして20gのFS−1を用い、これらを均一になるまで攪拌混合して、組成物(I)−1を得た。
